Installation

The WaveGuide Sensor

The WaveGuide radar can be positioned at any suitable mounting location  with  free space to the water. It is 
advised to choose a position such that the radar beam is free from large reflecting obstacles (beam width F08 

antenna 5 deg half top angle). This does not only includes horizontal objects in the beam , such as ducts, but also 
vertical structures as bridge pillars, quay walls, legs of an oil rig, etc. It is recommended to mount the WaveGuide 

at a minimum distance of  0,1x the height of the pole or qua wall.

 

The sensor has four mounting holes (

Ø

 11mm) in the top flange and lid equally distributed at a circle of 240mm  

To facilitate the mounting, a mounting plate and a rail

mounting are available.

Reference level for the measured distance to the water

surface is the bottom side of the sensor unit.
